Weighing Powder in Cold Temperatures

[Tennessee_Ted]

I’m getting my new reloading bench set up, and it’s in an unheated shop. I realized tonight that cool weather is causing problems with the inexpensive electronic scale I had been using for many years. It is drifting, and it is consistently weighing known objects about 3-4 grains heavy, even after calibration.

Since any scale I have will be subject to temperature variations, I assume it’s time to look at beam scales. I used to have a Lee that I didn’t care much for—that metal ball just didn’t seem like the most reliable counterweight. The RCBS beam scale seems to be a cut above the other big names out there, judging by the reviews on MidwayUSA.

Are beam scales very sensitive to temperature? And is there a particular one you would recommend?

TIA,
Ted

If your loading big batches, calibrate a powder throw and roll with it. Your drop should be well inside a tenth or two and a new scale is not required. I do this after my load development is done for a load. My problem is I do more testing than anything, making ladders of this or that. I use my chargemaster in my kitchen and once powdered go back in the garage.

I do the same. Have for decades. I use Redding balance scale.

My digital scale will drift some too. If the zero changes before my powder drop is set. I'll re zero the tare weight.

Most of the major reloading companies' beam scales are made by scale manufacturers.

Beam scales from Redding, RCBS, Dillon, and Lyman will serve you well.

Heat, cold, phones, or lights, don't effect beam scales operating on gravity, only moving air.

Thank you all for the replies.

How about a small portable heater in your loading area. Kerosene, propane or wood especially ones without an electric fan tso it doesn't effect the scale with a false wind.
